Radeon HD 4850 2GB vs Radeon HD 5830

Intro

The Radeon HD 4850 2GB has a core clock frequency of 625 MHz and a GDDR4 memory speed of 993 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 5830, which comes with GPU core speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Radeon HD 4850 2GB 63552 MB/sec
Difference: 64448 (101%)

Texel Rate

The Radeon HD 5830 is much (about 79%) more effective at anisotropic filtering than the Radeon HD 4850 2GB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 4850 2GB 25000 Mtexels/sec
Difference: 19800 (79%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5830 is a better choice, and very much so. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 4850 2GB 10000 Mpixels/sec
Difference: 2800 (28%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
